BACKGROUND

The collection of fluid or tissue samples is often required in the diagnosis and treatment of subjects suffering from many diseases and medical conditions. Sample collection from the mouth, nose, throat, and other locations may be accomplished by brushing or scraping a body surface with a swab. For example, some diseases may be detected by analysis of swabs, or fluid obtained from swabs, such as throat swabs, nasal swabs, cheek swabs, or other swabs, such as, influenza and other respiratory disorders; tuberculosis; bacterial infections such as diphtheria, whooping cough, and those caused be caused by staphylococcus, streptococcus, pneumococcus, and other bacteria; viral infections, such as, e.g., adenovirus infections; some genetic diseases caused by or related to a subject's genetic characteristics; and other diseases and disorders. Diseases may also be detected by analysis of urine samples, and other clinical samples.

Analysis of the sample typically requires that the collected fluid or tissue be transferred from the swab to a vessel, slide, or analysis device. However, such transfer is often incomplete, and loss or degradation of the sample may occur before analysis. Accordingly, improved swabbing methods and swab collection devices are required.

It is further noted that, as used in the specification and the appended claims, “or”, as used in “A or B”, refers to each of A; B; and A and B; that is, use of the word “or” includes “and/or” unless the context or an explicit statement clearly dictates otherwise. Thus, for example, reference to “treatment of cells or substrate” may include treatment of cells alone; treatment of substrate alone; and treatment of both cells and substrate.

References cited herein are hereby incorporated by reference in their entirety, except to the extent that they conflict with teachings explicitly set forth in this specification.

In this specification and in the claims which follow, reference will be made to a number of terms which shall be defined to have the following meanings:

As used herein, the terms “point of service” (abbreviated “POS”), “point of service location”, “point of care” (abbreviated “POC”), and “point of care location” may include locations where a subject may receive a service (e.g. testing, monitoring, treatment, diagnosis, guidance, sample collection, identification (ID) verification, medical services, non-medical services, etc.); may include locations where a subject may receive care (e.g., clinical care such as diagnostic and therapeutic care), and may include, without limitation, a subject's home, a subject's business, the location of a healthcare provider (e.g., doctor), hospitals, emergency rooms, operating rooms, clinics, health care professionals' offices, laboratories, retailers [e.g. pharmacies (e.g., retail pharmacy, clinical pharmacy, hospital pharmacy), drugstores, supermarkets, grocers, etc.], transportation vehicles (e.g. car, boat, truck, bus, airplane, motorcycle, ambulance, mobile unit, fire engine/truck, emergency vehicle, law enforcement vehicle, police car, or other vehicle configured to transport a subject from one point to another, etc.), traveling medical care units, mobile units, schools, day-care centers, security screening locations, combat locations, health assisted living residences, government offices, office buildings, tents, bodily fluid sample acquisition sites (e.g. blood collection centers), sites at or near an entrance to a location that a subject may wish to access, sites on or near a device that a subject may wish to access (e.g., the location of a computer if the subject wishes to access the computer), a location where a sample processing device receives a sample, or any other point of service location described elsewhere herein.

As used herein, the term “reagent” refers to an element, compound, or mixture which reacts with another substance, or aids in a reaction. A reagent may participate in, or aid a reaction, by providing one or more reactants of a chemical reaction; or by providing one or more agents which accelerate, modulate, quench or otherwise affect a chemical reaction; or by aiding reactants to dissolve, or to mix, or otherwise affect the ability of reactants to contact each other, or the extent of such contact; or by providing a diluent or other agent which may act to adjust the relative or absolute amounts of reactants participating in a reaction; or may have other effects or play another role in a reaction. A reagent may be solid, liquid, or gaseous; for example a reagent may be an aqueous solution including an agent which may engage in a chemical reaction with a target which may be present in a sample.

As used herein, the term “reagent vessel” refers to a structure configured to hold a reagent, e.g., for storage until the reagent is used. For example, where a reagent is a fluid (e.g., an aqueous reagent, a solvent, or other fluid) or a solid (e.g., a lyophilized reagent), a reagent vessel may be a vial, tube, or other container which may hold a desired amount of the reagent. A reagent vessel may include a cap, lid, or other closure.

As used herein, the term “mixing vessel” refers to a structure configured to hold material for mixing, e.g., to hold two or more materials at one time (e.g., a reagent and a sample). A mixing vessel may be useful for mixing two or more materials together. A mixing vessel may include a cap, lid, or other closure.

As used herein, a “waste container” or “waste vessel” refers to a container, of any suitable shape or size, configured to receive waste material (e.g., wash buffers after use, excess reagent, or other material). Such waste material may be stored in the waste container if desired, and may be transported to a disposal location for removal, or may be removed from a waste container for transport to a disposal destination.

As used herein, a “sample collection vessel” refers to a container, or device, configured to receive and retain a sample, such as, e.g., a nasal swab sample (or fluid containing material obtained from a nasal swab that had contacted a subject), a blood sample, a urine sample, a sputum sample, or other sample. A sample collection vessel may be configured to allow transport or transfer of a sample, or aliquot thereof, to another location or vessel.

As used herein, the term “implement” refers to a tool or device used during or for sample analysis. For example, an implement may be a cuvette, such as, e.g., a cytometry cuvette. For example, an implement may be a magnet, such as a magnetic bar (useful, e.g., for attracting beads or particles for isolation and concentration of target molecules in a sample). For example, an implement may be another tool or device.

As used herein, the term “cuvette” refers to a container having at least one optically translucent or transparent side, and configured to hold a sample for optical interrogation or inspection, or both.

As used herein, the term “cytometry cuvette” refers to containers having at least one optically translucent or transparent side, and configured to hold a sample (typically containing cells) for cytometric analysis; such cytometric analysis may include, e.g., microscopy, and other optical measurements and observations, such as, for example, measurements of fluorescence, optical scattering, optical absorption, optical transmittance, polarization, or other optical measurements.

As used herein, the term “assay unit” refers to a device configured for the performance of an assay; for example, an assay unit may be configured to hold sample and reactants for the performance of a chemical reaction for assaying the sample. In some cases, an assay unit may be a tubular or conical element having openings at each of two ends, the openings being connected by a channel, and containing a reagent or reagents. In embodiments, an assay unit may be configured to allow passage of light through a wall of the assay unit, and may be translucent or transparent (e.g., may have a wall, or portion of a wall, that is translucent or transparent); such passage of light may be useful in detection of an analyte, in detection of a label or marker bound to or connected with an analyte, or in detection or measurement of a concentration or other characteristic associated with an analyte, in a sample. For example, an assay unit may be configured to receive a portion of the sample (e.g., from a sample collection vessel) and may be configured to run a chemical reaction that yields a detectable signal indicative of the presence of an analyte in the sample. For example, an assay unit may be configured to run, or to participate in, an immunoassay. For example, an assay unit may be configured to run, or to participate in, a nucleic acid assay. For example, an assay unit may be configured to run, or to participate in, a general chemistry assay. For example, an assay unit may be configured to run, or to participate in, a cytometric assay.

As used herein, the term “pipette tip” refers to a tubular device having openings at each of two ends, the openings being connected by a channel; pipette tips may be cylindrical or have other shapes; for example, pipette tips are often tapered, and thus may have a conical shape. Pipette tips are useful for aspiration of fluids, and may be used to collect, transport, mix, or otherwise contact a fluid or fluids. In some embodiments, a wider end may be configured to engage a grasping or aspiration mechanism, providing mechanical support, transport, and/or fluid flow (e.g., suction or ejection) at or via the wider end. In some embodiments, a narrower end may be configured to contact a fluid, and may be configured for aspiration of fluid into the pipette tip via the narrower end. A pipette tip may include a filter or baffle within the channel so as to prevent contamination (e.g., either of a grasping or aspiration mechanism at one end of the pipette tip, or of fluid within or to be contacted by the pipette tip, or both). A pipette tip may be useful, for example, for aspiration of sample or other fluid, for mixing, for transport, or other uses.

As used herein, a “touch-off pad” refers to a location configured to drain or wipe excess fluid (e.g., reagent, diluent, sample, or other fluid) from a pipette tip. A touch-off pad typically includes an absorbent material for contacting a pipette tip, and is configured to wick or absorb liquid from the pipette tip upon contact between the pipette tip and the touch-off pad. A touch-off pad may be soft or resilient as well as absorbent. A touch-off pad may be made with, for example, paper (e.g., an absorbent paper such as a filter paper); fiber (e.g., either natural or artificial fiber woven or matted together); plastic; or other material.

As used herein, a “transport mechanism” refers to a device or system which may engage an object and move the object from one place to another. Sample handling systems (including fluid handling systems) may be, or include, a transport mechanism. A pipette having a nozzle may be used, for example, to engage a pipette tip (e.g., by pressure fit of the nozzle within a wider end of the pipette tip) effect to hold the pipette tip and to move the pipette tip from a first location to a second location. The pipette tip may be released from the nozzle at the second location (e.g., by movement of a ring or bar configured to push the pipette tip off of the nozzle).

As used herein, the term “transport unit” refers to a tool that is configured to hold one or more other objects for transport; for example, a transport unit may have a frame with holes or receptacles configured to retain one or more of a pipette tip, or an assay unit, or a mixing vessel, or a cuvette, or a waste vessel, or a sample collection vessel, or combinations of these. A transport unit may be configured to hold other objects for transport. A transport unit may be configured to interface with, and to be carried by, a transport mechanism (such as, e.g., a sample handling system or fluid handling system) which may include a means for grasping a transport unit, a means for transporting a transport unit to a desired location, and a means for depositing a transport unit at the desired location. Transport of a transport unit, where the transport unit retains one or more tips or vessels, or other implements, is effective to move such tips or vessels, or other implements, to a desired location. For example a transport unit may be configured to engage with a nozzle of a transport mechanism, e.g., in a way similar to that described for engagement of a pipette tip with a nozzle of a sample handling system.

As used herein, the term “sample” refers to a fluid, tissue, secretion, excretion, or other material collected from a subject. Examples of biological samples include but are not limited to, blood, serum, plasma, bone marrow, a nasal swab, a nasopharyngeal wash, saliva, urine, gastric fluid, spinal fluid, tears, stool, mucus, sweat, earwax, oil, a glandular secretion, cerebral spinal fluid, tissue, semen, vaginal fluid, interstitial fluids derived from tumorous tissue, ocular fluids, spinal fluid, a throat swab, breath, hair, finger nails, skin, biopsy, placental fluid, amniotic fluid, cord blood, lymphatic fluids, cavity fluids, sputum, pus, microbiota, meconium, breast milk and/or other secretions or excretions. Biological samples may include nasopharyngeal wash, or other fluid obtained by washing a body cavity or surface of a subject, or by washing a swab following application of the swab to a body cavity or surface of a subject.

Nasal swabs, throat swabs, stool samples, hair, finger nail, ear wax, breath, and other solid, semi-solid, or gaseous samples may be processed in an extraction buffer, e.g., for a fixed or variable amount of time, prior to their analysis. The extraction buffer or an aliquot thereof may then be processed similarly to other fluid samples if desired. Examples of tissue samples of the subject may include but are not limited to, connective tissue, muscle tissue, nervous tissue, epithelial tissue, cartilage, cancerous sample, or bone. The sample may be obtained from a human or animal. The sample may be obtained from a vertebrate, e.g., a bird, fish, or mammal, such as a rat, a mouse, a pig, an ape, another primate (including humans), a farm animal, a sport animal, or a pet. The sample may be obtained from a living or dead subject. The sample may be obtained fresh from a subject or may have undergone some form of pre-processing, storage, or transport.

A sample may be of any suitable size or volume, and is preferably of small size or volume. In some embodiments of the assays and methods disclosed herein, a sample may comprise a small volume sample, where a small volume comprises no more than about 5 mL; or comprises no more than about 3 mL; or comprises no more than about 2 mL; or comprises no more than about 1 mL; or comprises no more than about 500 μL; or comprises no more than about 250 μL; or comprises no more than about 100 μL; or comprises no more than about 75 μL; or comprises no more than about 50 μL; or comprises no more than about 35 μL; or comprises no more than about 25 μL; or comprises no more than about 20 μL; or comprises no more than about 15 μL; or comprises no more than about 10 μL; or comprises no more than about 8 μL; or comprises no more than about 6 μL; or comprises no more than about 5 μL; or comprises no more than about 4 μL; or comprises no more than about 3 μL; or comprises no more than about 2 μL; or comprises no more than about 1 μL; or comprises no more than about 0.8 μL; or comprises no more than about 0.5 μL; or comprises no more than about 0.3 μL; or comprises no more than about 0.2 μL; or comprises no more than about 0.1 μL; or comprises no more than about 0.05 μL; or comprises no more than about 0.01 μL.

Samples and Sample Analysis

Samples from the throat of a subject may be obtained, e.g., by a throat swab; samples obtained from the nose of a subject may be obtained, e.g., by a nasal swab. In embodiments, samples obtained from the throat and from the nose of a subject may be tested together. In embodiments, testing of samples obtained from the throat, or from the nose, or from both the nose and from the throat, may be tested by nucleic acid analysis; or by amino acid analysis (e.g., ELISA or other antibody-based or binding protein-based analysis); or by general chemistry analysis; or by cytometric analysis; or by combinations thereof. For example, samples may be tested by nucleic acid analysis and by amino acid analysis. Such tests may be used to determine how long a subject has had an infection, for example, by noting the delay in rise of levels of antibodies indicative of a particular disease in the sample; or by tracking the rise in the levels of antibodies indicative of a particular disease in the sample over time (e.g., by repeated testing over time). Similarly, such testing may be used to detect, or to determine, the effect of treatment, by noting the delay in rise of levels of antibodies indicative of a particular disease in the sample; or by tracking the rise in the levels of antibodies indicative of a particular disease in the sample over time (e.g., by repeated testing over time). In embodiments, samples from throat and from nose may be included in a single solution, and tested together. In embodiments, samples from throat and from nose may be in separate vessels (e.g., sample containers), but both included in a single cartridge, and the separate vessels tested at the same time. Such testing at the same time may comprise testing the vessels separately, or may include mixing the contents of the vessels and testing the mixture.

In embodiments, Applicants provide systems, methods, and devices for detecting a plurality of disease-causing agents in a single clinical sample, or in a plurality of aliquots of a single clinical sample. In embodiments, a single clinical sample may be a small volume clinical sample of blood, sputum, tears, nasal swabs, throat swabs, cheek swabs, or other bodily fluid, tissue, secretion, or excretion taken from a subject. In embodiments, a single clinical sample has a volume of less than about 500 μL, or less than about 250 μL, or less than 150 μL, or less than about 100 μL, or less than about 50 μL, or less than about 25 μL, or less than about 10 μL, or less than about 5 μL, or less than about 1 μL, or less.

In embodiments, clinical samples may be obtained at a point-of-service (POS) location. A POS location may be, for example, a retail pharmacy, a supermarket, a hospital, a clinic, a physician's office, or other location. Clinical samples may be tested at the POS location for multiple markers indicative of agents which may cause one or more of a plurality of diseases (e.g., at least 8, or at least 10, or at least 12, or at least 20, or at least 30, or at least 40, or at least 50, or at least 60, or more markers, indicative of the same or similar numbers of different diseases). The testing may be completed in a short period of time. In embodiments, the short period of time may be measured from the time the sample is inserted into a device or system for performing an analysis. In embodiments, the short period of time may be measured from the time the sample is obtained from the subject.

In embodiments, clinical samples may be analyzed at a POS location. In embodiments, clinical samples obtained at a POS location may be analyzed at the same POS location. In embodiments, clinical samples may be obtained at a point-of-service (POS) location and may be analyzed at a different location. In embodiments, clinical samples may be analyzed in a short period of time, e.g., in a period of time that is less than about 5 hours, or less than about 4 hours, or less than about 3 hours, or less than about 2 hours, or less than about 1 hour, or less than about half an hour.

Swab Containers

As shown in FIG. 1A, FIG. 1B, and FIG. 1C, a vessel for holding a swab may be loaded onto a cartridge, where it may be retained until needed for analysis; the cartridge may be loaded onto an analysis device or analysis system, thereby loading the swab (and any other samples or sample containers on the cartridge as well). FIGS. 1A, 1B, and 1C show exemplary containers for holding a swab (a swab container) and exemplary cartridges (which includes cavities and wells for reagents and vessels, and is configured to hold one or more of reagent vessels, assay units, mixing vessels, pipette tips, transport units, and other vessels and implements, including other sample vessels, e.g., blood or urine sample vessels). Arrows leading away from the swab container indicate how the swab container may be placed into a receptacle in the cartridge.

As shown in FIG. 1A, a vessel for holding a swab (a swab container 10) may be loaded onto a cartridge 20 by placement into a receptacle 30. The cartridge 20 as shown also includes cavities and wells 40 for receiving and holding reagents and vessels.

FIG. 2 shows views of an exemplary swab container 10 having a cover 12 flexibly attached to the conduit 14 near to the entry port 16. These figures also show an assay chamber 13 having an assay port 17, and a rib 15 of a swab container 10 which provides structural support to the swab container 10. FIG. 2A shows a side view, and FIG. 2B shows a top perspective view, while FIG. 2C provides an exploded view of a portion of the cover 12 (circled at “C” in FIG. 2A) showing a lip 18 which is configured to secure the cover 12 when the cover 12 is placed within the entry port 16 during closure of the entry port 16. Cover 12 may be closed over entry port 16 with all or a portion of a swab handle disposed within the interior channel 22 of a conduit 14; a handle may be broken if necessary to shorten the handle portion and to allow closure of the entry port 16. In embodiments, a cover 12 may fit entirely within an entry port 16; in other embodiments, a cover 12 may contact, and may at least partially cover, a rim 21 of an entry port 16. FIG. 2D provides an exploded view of the region circled at “D” in FIG. 2A, showing the linkage between a region near the entry port 16 and cover 12. The thinning of the neck portion shown in the expanded view shown in FIG. 2D facilitates flexing and bending of the linkage, and so aids in closure of the cover 12 over entry port 16. In the embodiment shown in FIG. 2, lip portion 18 fits within entry port 16, while tab 19 (which may be useful for manual manipulation of cover 12) may at least partially cover rim 21 when cover 12 is in place covering entry port 16. Cover 12 may be closed over entry port 16 with all or a portion of a swab handle disposed within the conduit; a handle may be broken if necessary to shorten the handle portion and to allow closure of the entry port 16.

It will be understood that a cover 12 may be attached to a swab container 10 by any suitable means, or may be a separate part that may be placed on or into an entry port 16. In embodiments, a cover 12 may be a rubber cover, or plug. In embodiments, a cover 12 may be an aluminized plastic sheet, or aluminum foil, or other cover glued, crimped, or otherwise disposed over an entry port 16.

An assay port 17 of a swab container 10 may be covered with a cover (not shown). For example, such a cover for an assay port 17 may be a pierceable cover (e.g., aluminum foil, or an aluminized plastic sheet, which may be attached by adhesive, crimped, or attached by other means to the assay chamber 16 or otherwise attached so as to extend over and cover assay port 17). In embodiments, such a cover for an assay port 17 may be a detachable cover (e.g., a rubber or plastic stopper or cap). In embodiments, a cover for an assay port 17 may be attached to a swab container 10 (e.g., may be attached to assay chamber 16).

A swab container as disclosed herein may be of any suitable size. A swab container 10 as shown, for example, in FIGS. 2A and 2B may have dimensions whereby the distance between an assay port 17 and an entry port 16 may be between about 25 millimeters (mm) and about 250 mm; or may be between about 50 mm and about 200 mm; or may be between about 75 mm and about 150 mm; or may be between about 80 mm and about 120 mm; or other distance. In embodiments, an assay chamber 13 may have a height of between about 10 mm and about 100 mm; or may have a height of between about 15 mm and about 75 mm; or may have a height of between about 20 mm and about 60 mm; or may have a height of between about 25 mm and about 50 mm; or other height. As shown in FIGS. 2A and 2B, an assay port 17 may have a circular shape. In embodiments, an assay port 17 having a circular shape may have a diameter, where the size of such a diameter may be, for example, between about 0.5 mm to about 25 mm; or between about 1 mm and about 20 mm; or between about 2 mm and about 15 mm; or between about 3 mm and about 10 mm; or other diameter. It will be understood, however, that an assay port 17 may have any suitable shape (e.g. circular, oval, square, rounded square, rectangular, rounded rectangular, triangular, rounded triangular, or other shape). The dimensions of assay ports of such other shapes (e.g., a side of a square, or rectangle, or triangle; or a long or short axis of an oval) will typically be found within similar ranges as the diameter ranges disclosed herein. As shown in FIGS. 2A and 2B, an entry port 16 may have an oval, or rounded rectangular, shape. It will be understood that an entry port 16 may have any suitable shape (e.g. circular, oval, square, rectangular, triangular, or other shape). In embodiments, an entry port 16 may have a dimension, such as a long axis, of between about 0.5 mm to about 25 mm; or between about 1 mm and about 20 mm; or between about 2 mm and about 15 mm; or between about 3 mm and about 10 mm; or other dimension.

An alternative embodiment of a swab container 10 is shown in FIG. 2E. A swab container 10′ as illustrated in FIG. 2E may be assembled for use from two parts, a forward portion (labeled “F”) and a rear portion (labeled “R”) which fit snugly together at mating point M. When assembled, a conduit 14 extends from entry port 16 to assay chamber 13. A swab container 10′ as shown in FIG. 2E may be dis-assembled (e.g., after insertion of a swab) into a forward portion F and a rear portion R; the forward portion R may be suitable for placement in a cartridge such as a cartridge 20 as illustrated in FIG. 1.

FIG. 3 shows a side view of a swab container 10 having an entry port 16; in this embodiment, the entry port 16 lacks an attached cover. In embodiments, a detachable cover 33 may be placed in or on the entry port 16. In embodiments, such a detachable cover 33 may include a rubber stopper, or plastic lid, or may be a pierceable cover (e.g., aluminum foil, or an aluminized plastic sheet, which may be crimped, or attached by adhesive or by other means to rim 21 of entry port 16). In embodiments, a cover 33 may be a porous cover, such as, e.g., filter paper, or gauze, or mesh, or other porous or semi-porous cover placed so as to cover the entry port 15). It will be understood that a swab container 10 as illustrated in FIG. 3 may also have a cover over assay port 17 (not shown). FIG. 3A provides a side view, and FIGS. 3B and 3C provide cross-sectional views showing the interior channel 22 within the conduit 14 of the swab container 10. A portion of an interior channel 22 may have a narrowing, as indicated by arrow 33 in FIG. 3A, and as shown in the cross-sections of FIGS. 3B and 3C. FIG. 3B provides a cross-section taken along a line as indicated by the arrow labeled “B” in FIG. 3A, showing the narrowing of the interior channel 22 near the assay chamber 13. FIG. 3C provides a cross-section taken along a line as indicated by the arrow labeled “C” in FIG. 3A, showing the interior channel 22 near the entry port 16; the interior channel 22 is narrower near the assay chamber 13 (see FIG. 3B) than it is near the entry port 16 (see FIG. 3C); such narrowing (e.g., as indicated by arrow 33) is configured to squeeze a swab (e.g., a swab tip) pushed through or in place in the interior channel 22, effective to aid in the release of sample material carried by the swab. In embodiments, such a narrowing may be configured to prevent the entry of a swab (e.g., a swab tip) into an assay chamber 13. Such a narrowing of an interior channel 22 may be accomplished by, e.g., a symmetric narrowing of the channel; an asymmetric narrowing of the channel; by inclusion of a feature (e.g., a protrusion such as a bump, a wedge, a knob, a baffle, rib, or other feature) in a wall of the interior channel, wherein the feature may be oriented longitudinally along the channel wall, laterally along the wall, or at some other orientation relative to a longitudinal axis of the channel; by a bend in the channel; or by other means, or by a combination of means. In some embodiments, the interior channel 22 narrows to a size wherein the swab does not enter the assay chamber 13 when the swab is fully inserted. Such an embodiment may have fluid communication between the channel and the assay chamber 13 but the swab does not physically enter the assay chamber 13. Optionally, some embodiments may allow for at least a portion of the swab to enter the assay chamber 13.

FIG. 3A also shows contact angle 24 between conduit 14 and assay chamber 13. A contact angle 24 may be any suitable angle. In embodiments, a contact angle 24 may be between about 10° to about 90°. In embodiments, a contact angle 24 may be between about 40° to about 85°. In embodiments, a contact angle 24 may be between about 70° to about 80°. In the embodiment shown in FIG. 3A, the contact angle is about 75°.

FIG. 4 provides a top perspective view (FIG. 4A) and a cross-sectional view (FIG. 4B) showing one embodiment of a swab container 10 having a conduit 14 having two interior channels 22 connecting entry port 16 with assay chamber 13. As shown, cover 12 in FIG. 4A may be used to close off entry port 16, sealing both interior channels 22. In embodiments, a cover 12 may be configured to close only a single interior channel 22, e.g., to allow closure of a first interior channel 22 after placement of a first swab therein, while allowing continued access for placement of a second swab in a second interior channel 22. For example, in embodiments, a cover 12 may be configured to close only a single interior channel 22 at a time (e.g., may be split into two portions which may close independently of each other, allowing closure of a first interior channel 22 after placement of a first swab therein, while allowing continued access to second interior channel 22; the second portion of such a cover 12 may be closed following placement of a second swab in a second interior channel 22 or at any other desired time). In embodiments, a swab container 12 may include two covers 12 which may be positioned independently of each other.

It will be understood that, in further embodiments, a swab container may hold two swabs in a single interior channel; or a swab container may hold three or more swabs in a single interior channel. The orientation of the swabs in the same channel may be top-bottom, side-by-side, diagonally oriented, or other configuration depending in part on channel cross-sectional shape. As shown in the examples of FIGS. 4A and 4B, a swab container configured to hold two swabs may have conduits (and interior channels) that are substantially parallel to each other (e.g., the long axes of the conduits (and interior channels) form an angle with respect to each other of less than about 5°). In further embodiments, a swab container configured to hold two, to hold more than two, swabs, may have conduits (with interior channels) which are not substantially parallel, but are placed at angles to one another. For example, a pair of conduits (of a swab container having two, or three, or more conduits) may be substantially perpendicular to one another (e.g., may have long axes that form an angle close to 90°, that is, between about 85° and about 95°), or may form an angle of about 45°; or may form an angle of between about 5° to about 175°; or may form any other angle. In embodiments, a swab container configured to hold two, or configured to hold more than two, swabs, may have conduits (with interior channels) with long axes which are substantially in line with each other on opposite sides of an assay chamber (e,g, the long axes form an angle of between about 175° to about 185°). In embodiments, such swab containers having two, three, or more conduits may have interior channels each of which connect with the same assay chamber. In embodiments, such swab containers having two, three, or more conduits may have interior channels which connect with the different assay chambers.

It will be understood that placement of a swab into a swab container 10 allows transfer of sample material into a reagent, e.g., a fluid, for transport to another location or to a sample analysis device, or for analysis in the assay chamber 13 itself. An assay chamber 13 may be filled (to any desired degree, e.g., either partially or completely) with a reagent for bathing a swab (i.e., for bathing at least a tip of a swab); an interior channel 22 may be filled (to any desired degree, e.g., either partially or completely) with a reagent for bathing a swab; such a reagent may be or include, for example, a transport medium (such as, e.g., Copan Universal Transport Medium® (UTM-RT) (Copan Diagnostics Inc., Murrieta, Calif., USA) or other transport medium), saline, distilled water, or other reagent suitable for bathing a swab. A reagent for bathing a swab may aid in releasing sample material from the swab for analysis. Such release of sample into a reagent provides fluid containing sample material which may be used for sample analysis. The reagent containing sample material may then be used to transport the fluid to a location or device for analysis, or the swab container itself may be used, at least in part, for analysis of the fluid. It should be understood that although the term assay chamber is used herein, at least some embodiments are configured to perform only sample preparation in the chamber and that the assay itself will be performed elsewhere. In this non-limiting example, sample is prepared in the assay chamber and at least one portion of the prepared sample is extracted from the assay chamber for performing assay(s) at another location. It should also be understood that if a fluid is used in the assay chamber 13, the fluid level may be selected so that at least a portion of the handle of the swab is also bathed in the fluid when the swab is fully inserted. In this non-limiting example, sample on the handle can also be drawn into the fluid and increase the amount of sample in the fluid, which can be helpful when the amount of sample collected is small. In one embodiment, at least 10% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 20% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 30% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 40% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 50% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 60% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 70% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 80% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 90% of the length of the handle is covered by the fluid when the swab is fully inserted. Optionally, at least 95% of the length of the handle is covered by the fluid when the swab is fully inserted.

Thus, for example, an assay chamber 13, interior channel 22, or both, may contain water; or an assay chamber 13, interior channel 22, or both, may contain a water solution including salts, or buffers, or surfactants, or solvents, or emulsifiers, or other elements. An assay chamber 13, interior channel 22, or both, may contain a reagent for bathing a swab, such a reagent including a salt, or combination of salts, such as physiological salts (e.g., Hank's Balanced salts, or other salt combination providing salt concentrations near to normal mammalian physiological salt concentrations). In embodiments, the salt concentration of a reagent for bathing a swab may be a low concentration as compared to normal mammalian physiological salt concentrations. In embodiments, the salt concentration of a reagent for bathing a swab may be a high concentration as compared to normal mammalian physiological salt concentrations. A reagent for bathing a swab may include serum albumin or other serum product, such as, e.g., bovine serum albumin, fetal calf serum, horse serum, or the like. A reagent for bathing a swab may include gelatin. A reagent for bathing a swab may include sucrose, or glucose, or other sugar, saccharide, or oligosaccharide. A reagent for bathing a swab may include an antibiotic, such as, e.g., amphotericin, valnomycin, vancomycin, colistin, streptomycin, gentamycin, iodine, or other antimicrobial agent. A reagent for bathing a swab may include a preservative (e.g., benzoic acid, benzyl alcohol, phenol alcohol, butyl alcohol, an alkyl paraben such as methyl or propyl paraben, an ammonium chloride compound, m-cresol, resorcinol, catechol, cyclohexanol, sodium azide, chemical derivatives thereof, or other preservative). A reagent for bathing a swab may include amino acids such as, e.g., cysteine, glutamic acid, glutamate, or other amino acid. A reagent for bathing a swab may include a buffer, such as, e.g., a phosphate, citrate, ammonium, acetate, or carbonate buffer; tris(hydroxymethyl)aminomethane (TRIS); 3-(N-morpholino) propanesulfonic acid (MOPS); 3-morpholino-2-hydroxypropanesulfonic acid (MOPSO); 2-(N-morpholino)ethanesulfonic acid (MES); N-(2-Acetamido)-iminodiacetic acid (ADA); piperazine-N,N′-bis(2-ethanesulfonic acid) (PIPES); 4-(2-hydroxyethyl)-1-piperazine ethanesulfonic acid (HEPES); or other buffer. For example, a reagent for bathing a swab may include a buffered aqueous solution (e.g., a saline solution) having a pH of between about pH 4 to about pH 10; or between about pH 5 to about pH 9; or between about pH 6 to about pH 8; or between about pH 6.7 to about pH 7.7; or other pH. A reagent for bathing a swab may include a pH indicator (e.g., phenol red, or other indicator). In embodiments, a reagent for bathing a swab may be, or may include a non-aqueous medium (e.g., may be or include ethanol, or dimethylsulfoxide, or other compound).

Accordingly, Applicants disclose swab containers including a reagent for bathing a swab. Such swab containers may have features as disclosed herein, including, but not limited to, any or all features of swab containers 10 as illustrated in any of the figures provided herein. In embodiments, a reagent for bathing a swab may be contained within at least a portion of an assay chamber of a swab container. In embodiments, a reagent for bathing a swab may be contained within at least a portion of an interior channel of a swab container. In embodiments, a reagent for bathing a swab may be contained within at least a portion, or portions, of both an assay chamber and an interior channel of a swab container.

FIG. 5 provides an example of a swab container configured to receive a swab (the container is shown without a swab in FIG. 5A, while a swab 24 is shown in place in the assay chamber 13 in FIG. 5B. The swab shown in FIG. 5B has a break-point 140 within conduit 14 and below the level of the entry port 16. In the embodiments shown in FIG. 5, the entry port 16 provides a swab 24 with access to an assay chamber 13 via a conduit 14 having an interior channel 22 within conduit 14. A cover 12 flexibly attached to the conduit 14 near the entry port 16 is shown. A cover 12′ that has a tab 19′ for ease of handling is also shown covering access channel 26, and may be a pierceable cover 12, is better seen in FIG. 5B. Assay chamber 13 is in fluidic contact with entry port 16 (via interior channel 22) and with assay port 17 via access channel 26. In the embodiments shown in FIG. 5, assay port 17 is occluded by a stopper 23 with needle 28; fluidic access to assay chamber 13 is via needle 28.

As indicated by the darker shading and the fill-lines shown in FIGS. 5A and 5B, an assay chamber 13 (and an access channel 26) may be at least partially filled with a reagent 25; such a reagent 25 may be a reagent for bathing a swab as discussed above (e.g., a transfer medium, saline, distilled water, or other reagent). Thus, a reagent 25 may aid in releasing sample material from the swab for analysis. Such release of sample material into a reagent 25 provides fluid containing sample material which may be used for sample analysis. Access to the reagent 25 containing a sample obtained from a swab 24 may be via assay port 17 and access channel 26. An access channel 26 may have a needle 28 positioned therein, as shown in FIGS. 5A and 5B. In embodiments, access to the reagent 25 containing a sample obtained from a swab 24 may be by way of a pipette, or suction tube, or capillary tube, or siphon, or other means. For example, a vial (e.g., a vial having a rubber cap or other pierceable cap) may be placed into access channel 26 and onto needle 28 for drawing fluid out of the assay chamber 13. Such a vial may, for example, have a partial or total vacuum prior to piercing a pierceable cap, effective that puncture of the vial's pierceable cap by needle 28 allows fluid from assay chamber 13 to be drawn into such a vial. A stand 29 may stabilize or otherwise aid in the use of a swab container 10 as shown in FIGS. 5A and 5B. The container may then be used to transport the fluid to a location or device for analysis, or the container itself may be used, at least in part, for analysis of the fluid.

FIG. 5A also shows contact angle 24 between assay chamber 13 and access channel 26. A contact angle 24 may be any suitable angle. In embodiments, a contact angle 24 may be between about 2° to about 90°. In embodiments, a contact angle 24 may be between about 5° to about 75°. In embodiments, a contact angle 24 may be between about 7° to about 40°. In embodiments, a contact angle 24 may be between about 10° to about 20°. In the embodiment shown in FIG. 5A, the contact angle is about 15°.

Swabs may be any suitable swab for collection of a sample. As shown in FIG. 6, swabs may have different kinds of tips; may have different kinds of handles; may have different lengths; and may have other differences. For example, swabs may be made of many different materials: for example, swab tips may be cotton, plastic, polymer, or other material or combination of materials; and swab handles may be wood, paper, plastic, polymer, or other material or combination of materials. Several examples of swabs suitable for use in sample collection are shown in FIG. 6. Such swabs, and other swabs, may be used to obtain samples from the throat, nasal passages, cheeks, or other body locations of subjects. Swabs with flocked tips (swab 100, and the shorter swab 200, suitable for pediatric use), or those also suitable for use in establishing cultures of material obtained by swabbing a body cavity or surface of a subject (swab 300), cotton-tipped swabs (swab 400), and other swabs may be used to collect a sample from a patient for use with the methods, systems, and devices disclosed herein. Swabs may include a portion, or position, configured for breakage (e.g., a place, typically along the handle, which is weaker, thinner, scored, or otherwise more liable to break when bent, twisted, or pulled) which provides a longer handle for use while obtaining a sample with the tip of the swab, while also allowing the swab to be shortened after a sample is obtained (e.g., to better fit within the interior channel of a conduit of a swab container as disclosed herein).

As shown in FIG. 6, swab tips 110, 210, 310, and 410, although similar, may differ in shape, length, and width as well as in material. Swab tips 110, 210, 310, and 410 are attached to shafts 120, 220, 320, and 420 respectively; the shafts are connected to, and are typically seamlessly integrated with, handles 130, 230, 330, and 430. Some swabs may include a break-point (e.g., swabs 100 and 200 include break-points 140 and 240, respectively) configured to allow easy shortening of a swab (which is useful, e.g., after sample collection) by breaking the shaft 120 or 220 at a break-point 140 or 240, in order to separate the shaft 120 or 220 from the handle portion 130 or 230.

FIG. 7 shows a cartridge 20 having a cover 61 and configured to accept a swab container. FIG. 7A shows such a cartridge 20 with its cover 61 closed, and with a swab container 10 in place in the swab container receptacle 30 (and the swab container cover 61 closed). FIG. 7B shows a swab 500 being placed into the swab container 10 (with its cover 12 open, to allow receipt of the swab 500 into entry port 16); a sample collection vessel 50 is also shown in position for placement into a sample collection vessel receptacle 51 in the cartridge 20. The cartridge 20 shown in FIGS. 7A and 7B has a guide 62 which is configured to aid in the proper placement of the cartridge 20 in a sample processing device or a sample analysis device, or other device or system which may receive the cartridge. A cartridge 20 may have a pair of guides, one on each of two opposite sides of the cartridge (e.g., a guide 62 as shown in FIGS. 7A and 7B, and a further guide in a similar or symmetric location on the opposite side (not shown in the figures). In embodiments, a cartridge 20 may have more than two such guides; for example, a cartridge 20 may have two pair of such guides. The guides 62 of FIGS. 7A and 7B are shown as slots; however, it will be understood that a guide 62, or a pair of guides 62, or a plurality of guides 62 may include slots (as shown), rails, slides, pegs, pins, and other elements. Such elements may be configured to slide into, or slide over, or to mate with, or otherwise operably engage complementary elements in or on a sample processing device or a sample analysis device, or other device or system which may receive the cartridge. In one non-limiting example, the guide can be “keyed” to have a specific cross-sectional shape such that cartridge 20 can only be received into the device in a specific orientation. Optionally, some embodiments, may have different shaped and/or sized features on each side of the cartridge 20 so that the orientation in which the cartridge in inserted can be controlled. Some embodiments may have this feature only along one surface of the cartridge. Some may have the feature along a lower or upper portion to minimize the risk that the cartridge is inserted upside-down. In this manner, a user is directed to insert the cartridge 20 in the correct manner.

FIG. 8 shows a cartridge 20 with its cover 61 open; the cartridge 20 has a swab container receptacle 30 containing a swab container 10 (with its swab container lid 12 closed), and also contains a sample collection vessel 50 in a sample collection vessel receptacle 51.

FIG. 9 shows an embodiment of a swab container 11, illustrating several configurations during use. FIG. 9A shows a closed swab container 11; in the closed configuration, the lid 12 covers entry port 16 leading to interior channel 22, but access to assay port 17 and thus to assay chamber 13 remains open. Interior channel 22 is in fluid communication with assay chamber 13 of the swab container 11, e.g., as indicated by the arrow F in FIGS. 9A and 9E (the arrows, and other indicator lines and numerals are not shown in all figures for simplicity of illustration, but indications in one figure may be used to identify similar features in other figures). A cover 12 of a swab container 11 may be configured for manual manipulation; for example, a cover 12 may have raised features 53, and may have a handle 55, as shown, which aid in engaging and moving a cover 12 by hand. In embodiments, a cover 12 may have depressions, or notches, or a raised shaft or shafts, or another feature or features configured to aid in its manual manipulation (e.g., to aid manual sliding of a cover 12 to open or closed configurations).

FIG. 9B shows an open swab container 11 with the cover 12 slid to expose entry port 16 leading to interior channel 22; in this configuration, cover 12 closes off assay port 17 and thus encloses the outer portion of assay chamber 13.

FIG. 9C shows an open swab container 11 with a swab 500 having a swab tip 510 and a swab shaft 520, the swab tip 510 being partially inserted into the interior channel 22 of the swab container 11.

FIG. 9D shows the swab container 11 with its cover 12 partially closed. The cover 12 has sharp edges 57 in position and ready to sever the shaft 520 of a swab 500 that is in place with swab tip 510 and a portion of swab shaft 520 within the interior channel 22.

FIG. 9E shows a swab container 11 in a closed configuration with a pipette 520 in place in the assay chamber 13 (via assay port 17). Interior channel 22 is in fluid communication with assay chamber 13; thus, when a reagent (e.g., a reagent for bathing a swab) is present in interior channel 22, a pipette 530 inserted into an assay chamber 13 via assay port 17 is in position to remove at least a portion of the reagent. A reagent removed by a pipette 530 may include, for example, sample material obtained from a subject; the interior channel 22 may have held a reagent that had bathed a swab tip 510 after the swab tip 510 had contacted a subject (e.g., had contacted a subject's nasal passages or other portion of a subject).

In embodiments, an interior channel 22 and an assay chamber 13 may be at least partially filled with a reagent for bathing a swab prior to placement of a swab tip 510 in an interior channel 22. In embodiments, a pipette 530 may carry or otherwise provide a reagent and may be used to at least partially fill an assay chamber 13 (and thus to at least partially fill an interior channel 22 which is in fluid communication with the assay chamber 13). In embodiments, such filling may be, e.g., prior to placement of a swab tip 510 within the interior channel 22. In embodiments, such filling may be, e.g., after placement of a swab tip 510 within the interior channel 22.

FIG. 10 shows an example of a cartridge 20 with its cover 61 open, showing a swab container 11 and indicating that the swab container 11 can fit into the swab container receptacle 30 as illustrated. A sample collection vessel 50 is also shown in place in a sample collection vessel receptacle 51.

FIG. 11 shows an example of a cartridge 20′ having two swab container receptacles 30 and 30′, and indicating that each of the swab containers 10 and 10′ can each fit into a swab container receptacle (either 30 or 30′). Other receptacles (e.g., 40) may hold other vessels and containers (e.g., a sample collection vessel 50 in a sample collection vessel receptacle 51 as shown) or may be configured to hold fluids or other materials in the absence of a vessel or other container. It will be understood that, in further embodiments, a cartridge may include a single swab container receptacle that is configured to hold two swab containers. In yet further embodiments, a cartridge may include a single swab container receptacle that is configured to hold three, or more, swab containers.

Devices for use in performing assays for detecting one or a plurality of disease-causing agents as disclosed herein. In embodiments, such devices for use in performing assays for detecting one or a plurality of disease-causing agents comprise cartridges, wherein the cartridges may further a space, or a container, for holding a swab (e.g., may include a receptacle configured to receive and retain a swab container, and may include a swab container in the receptacle). Thus, in embodiments, a cartridge may be configured to hold a swab container; the swab container may include a swab held therein, or may be empty of a swab (e.g., may be ready to receive a swab. In embodiments, a cartridge may include one, two, or more space(s) for holding two swabs, or a plurality of swabs, where such a space or spaces may include one or more receptacle(s) configured to receive and retain a swab container, or a plurality of swab containers, and may include a swab container or a plurality of swab containers in the receptacle or receptacles. In embodiments, a single swab may be placed in a single space, or a single swab container; in embodiments, two swabs may be placed in a single space, or single swab container; and in embodiments, a plurality of swabs may be placed in a single space, or single swab container. In embodiments, a plurality of swabs may be placed in a plurality of spaces, or in a plurality of swab containers. Such a swab container, or such swab containers, may contain a reagent, or a diluent, or other solution for use with a swab or swabs. Thus, in embodiments, a swab container may be prepared for use by including an amount of reagent, such as, e.g., a reagent for bathing a swab, within the swab container. In embodiments, a reagent for bathing a swab may be disposed within an assay chamber of a swab container. In embodiments, a reagent for bathing a swab may be disposed within an interior channel of a swab container. In embodiments, a reagent for bathing a swab may be disposed within an assay chamber and within an interior channel of a swab container.

In embodiments, a cartridge for use in performing assays for detecting one or a plurality of disease-causing agents may include a swab container. In embodiments, a cartridge for use in performing assays for detecting one or a plurality of disease-causing agents may include a swab container, and may further include a swab. A swab included in a cartridge may be an unused swab, ready for use in collecting a sample form a subject. In embodiments, a cartridge may carry a swab (e.g., within a swab container) after the swab has been used to collect a sample from a subject; for example, after collection, a swab may be placed within a swab container, and the swab container placed in a receptacle in a cartridge. Such a cartridge may then be placed in a sample processing device, an analysis device, or other device or system for processing and analysis.

For example, a throat swab or a nasal swab may be used to collect a sample from the throat or nasal passage of a subject. A nasal swab may be useful for testing for upper respiratory diseases, and a throat swab may be useful for testing lower respiratory diseases. In embodiments, the throat swab or the nasal swab may be placed in a swab container, and the swab container may be placed in a cartridge. The swab container may contain a reagent, or a diluent, or other solution for use with the swab. The cartridge may be placed in a sample processing device, an analysis device, or other device or system, for processing and/or analysis. Such processing and analysis devices and systems may be located at the same location as the location in which the sample was obtained; or such devices and systems may be located at a different location or locations than the one at which the sample was obtained.

For example, both a throat swab and a nasal swab may be used to collect a sample from the throat and from a nasal passage of a subject. In embodiments, the throat swab may be placed in one cartridge, and the nasal swab may be placed in a different cartridge. In embodiments, the cartridge may have two or more interior channels; in such embodiments, the throat swab may be placed in one interior channel of a cartridge, and the nasal swab may be placed in a different interior channel of that cartridge. The swab container may contain a reagent, or a diluent, or other solution for use with the swabs; such reagents may be different for the throat swab and the nasal swab. In embodiments, reagent for use with a throat swab may be held within the interior channel containing the throat swab, and reagent for use with a nasal swab may be held within the interior channel containing the nasal swab. The cartridge may be placed in a sample processing device, an analysis device, or other device or system, for processing and/or analysis. Such processing and analysis devices and systems may be located at the same location as the location in which the sample was obtained; or such devices and systems may be located at a different location or locations than the one at which the sample was obtained.
